An object is to provide a methane synthesis device having as a whole a reduced size and a simplified configuration. A methane synthesis deviceis composed of respective components from an end plateat the leftmost side to an end plateat the rightmost side and is compactly assembled by fastening plural bolts and nuts to bring these individual components into tightly contact with each other. The components may be divided into a Sabatier reaction unit of signsto, a water electrolysis unit of signsto, and other components. Hydrogen gas generated in the water electrolysis unit is mixed with carbon dioxide gas and supplied to the Sabatier reaction unit, and methane is synthesized in the Sabatier reaction unit. The size of the device is reduced as a whole and configuration is simplified by integrally stacking the water electrolysis unit, the Sabatier reaction unit, a carbon dioxide supplying unit, and a hydrogen gas supplying unit.

A plasma CVD apparatus efficiently coats the surfaces of fine particles with a thin film or super-fine particles by concentrating a plasma near the fine particles. The plasma CVD apparatus includes a chamber, a container disposed in the chamber for housing the fine particles, the container having a polygonal inner shape in a cross section substantially perpendicular to a longitudinal axis of the container, a ground shielding member for shielding a surface of the container other than a housing face, a rotation mechanism for causing the container to rotate or act as a pendulum on an axis of rotation substantially perpendicular to the cross section, an opposed electrode disposed in the container so as to face the housing face, a plasma power source electrically connected to the container, a gas introducing mechanism for introducing a raw gas into the container, and an evacuation mechanism for evacuating the chamber.
